III. Background, Basis, and Purpose 

This notice of proposed rulemaking 

(NPRM) incorporates by reference 

updated marine engineering standards 

in Title 46 of the Code of Federal 

Regulations (CFR) subchapter F, 

including standards for boilers, pressure 

vessels, auxiliary machinery, piping, 

valves, and fittings, for various types of 

vessels; adds a limited number of 

alternative standards; and eliminates 

outdated or unnecessarily prescriptive 

regulations. 

The Office of Management and Budget 

(OMB) directs, via OMB Circular A–119, 

that federal agencies use industry-based 

voluntary consensus standards in lieu of 

government-unique requirements where 

appropriate. The Coast Guard actively 

participates in the development of 

industry standards of safety for marine 

equipment at the International Maritime 

Organization (IMO), the International 

Organization for Standardization (ISO), 

ASTM International (ASTM), American 

Society of Mechanical Engineers 

(ASME), and other standards-setting 

bodies that belong to the American 

National Standards Institute (ANSI). 

Recently published editions of these 

standards provide necessary updates to 

materials, testing practices, and 

technologies, enhancing safety and 

compliance.

The United States Coast Guard has 

statutory authority to promulgate 

regulations under Title 43, United States 

Code (U.S.C.), section 1333(d); and Title 

46 U.S.C. 3306 and 3703, and the 

Department of Homeland Security 

Delegation No. 0170.1, which delegates 

authority under these statutes to the 

Commandant of the Coast Guard. 43 

U.S.C. 1333(d) grants the Secretary the 

authority to promulgate and enforce 

regulations with respect to lights and 

other warning devices, safety 

equipment, and other matters relating to 

the promotion of safety of life and 

property on artificial islands, 

installations, and other devices. 46 

U.S.C. 3306(a)(1) authorizes the 

Secretary to prescribe regulations for the 

design, construction, alteration, repair, 

and operation of vessels subject to 

inspection, including equipment, 

appliances, propulsion machinery, 

auxiliary machinery, boilers, unfired 

pressure vessels, piping, and electric 

installations. Additionally, 46 U.S.C. 

3703(a) grants the Secretary authority to 

regulate tank vessels regarding the 

construction, alteration, repair, 

maintenance, operation, and equipping 

of vessels that may be necessary for 

increased protection against hazards to 

life and property, for navigation and 

vessel safety, and for enhanced 

protection of the marine environment. 

IV. Discussion of Proposed Rule 

A. General Discussion 

In general, the proposed rule would 

make the following changes: 

1. Corrections—we would amend 

several sections to correct inadvertent 

errors or deletions. We would also 

remove material that is obsolete or 

superfluous to an efficient and effective 

marine safety regulatory scheme, and 

update contact information for Coast 

Guard offices and standards 

organizations. 

2. Stylistic Revisions—we would 

revise the language of some sections, 

primarily for greater clarity. This 

includes revising sentences containing 

the word ‘‘shall’’ to use ‘‘must’’ or 

another grammatically equivalent word 

or phrase in accordance with plain 

language guidelines, and standardizing 

terms that were variously presented as 

compound words, hyphenated 

constructions, or multi-word phrases 

using the format preferred by the 

Government Publishing Office (GPO). 

3. Updated cross references—we 

would update cross references to reflect 

the relocation, within the CFR, of 

pertinent provisions. We would also 

standardize designations for tables, 

figures, notes, and formulas using the 

format preferred by the Office of the 

Federal Register (OFR). 

4. Updated industry standards—we 

would update cross-references to 

industry standards by adding new 

references, replacing references to 

superseded standards or editions, and 

by conforming text accordingly. We 

incorporate these updated standards 

because they reflect the latest available 

technologies, practices, and procedures 

that are recommended by consensus 

bodies, ship classification societies and 

other maritime organizations with 

experience in the industry. As the 

baseline upon which other standards, 

rules, and equivalency requests are 

evaluated, it is important that 

subchapter F incorporate up-to-date 

references. The class rules of the 

American Bureau of Shipping (ABS), in 

particular, are incorporated by reference 

in multiple locations within subchapter 

F and 46 CFR Chapter I. It is important 

to note that while these rules set the 

regulatory baseline or standard for 

specific engineering systems and 

equipment, the Coast Guard has also 

authorized classification societies in 

accordance with 46 CFR part 8. These 

authorized classification societies are 

listed on the Coast Guard website 1 and 

have been delegated the authority to 

perform certain functions and 

certifications using their respective class 

rules for vessels enrolled in the 

Alternate Compliance Program. For 

vessels not enrolled in the Alternate 

Compliance Program, the class rules of 

an authorized classification society may 

be proposed as an alternative to the ABS 

class rules incorporated by reference for 

engineering systems and equipment. 

The following table indicates the 

sections we propose to amend, and why.

58.30–15, 59.10–5, and 59.10–10. By 

means of this rule, we propose to 

remove the references at §§ 54.01–15, 

56.20–1, and 56.30–30. The 1989 

edition is also incorporated by reference 

at §§ 64.5, 64.11, 64.13, 64.21, 64.25, 

and 64.31, and reference is made to the 

use of a constant from the 1974 edition 

in a calculation at § 64.63. However, 

these earlier editions would remain 

unchanged within the CFR, as part 64 is 

applicable only to marine portable tanks 

for which the Coast Guard’s Marine 

Safety Center (MSC) received an 

application on or before May 1, 1991. 

This code contains requirements, 

specific prohibitions, and nonmandatory guidance for construction of 

pressure vessels. It has been regularly 

revised to accommodate technological 

developments, to address administrative 

requirements, to incorporate 

interpretations, and to clarify the intent 

of the code. It is the internationally 

accepted authoritative standard for 

design and construction of heating 

boilers. Incorporating the latest editions 

ensures compliance with current 

industry practices. The 2019 edition 

allows for additional design methods 

from Div. 2 to be used in Div. 1 by 

creating new appendix 46. Revisions 

were also made for clarity. 

• ASME Boiler and Pressure Vessel 

Code, Section IX, Welding, Brazing, and 

Fusing Qualifications (2019 edition).

1,57.02–2, 57.02–3, 57.02–4, 57.03–1, 

57.04–1, 57.05–1, 57.06–1, 57.06–3, 

57.06–4, and 59.10–5. By means of this 

rule, we propose to newly incorporate 

this standard at § 56.85–10 and to 

remove the references at §§ 57.01–1, 

57.02–3, and 57.06–3. This standard 

establishes the qualifications of welders, 

welding operators, brazers, and brazing 

operators and the procedures employed 

in welding or brazing, and has been 

regularly revised to accommodate 

technological developments, address 

administrative requirements, 

incorporate interpretations, and clarify 

the intent of the code. It is the 

internationally accepted authoritative

• ASME B1.1–2003 (reaffirmed 2008), 

Unified Inch Screw Threads (UN and 

UNR Thread Form). This standard 

updates the 1982 edition, incorporated 

by reference at §§ 56.25–20 and 56.60– 

1, and specifies the thread form, series, 

class, allowance, tolerance, and 

designation for unified screw threads. 

The revision changes some of the values 

in tables provided in the standard. 

These changes in value were the result 

of the application of consistent eight 

decimal and round rules established in 

ASME B1.30–1992. 

• ASME B1.20.1–2013, Pipe Threads, 

General Purpose (Inch). This standard 

updates the 1983 edition incorporated

Manufacturers Standardization Society 

of the Valve and Fittings Industry 

(MSS), respectively. 

Section 54.01–15 Exemptions From 

Shop Inspection Plan Approval 

(Modifies U–1(c)(2)) 

Deleting paragraph (a)(3)(i) because 

this section deals with internal pressure 

and the reference cited deals with 

external pressure. 

Section 54.01–18 Plan Approval 

Editing paragraph (a) to provide 

reference to new proposed paragraph 

(c).

Modifies UG–92 Through UG–103) 

Editing the section heading to make it 

easier to find the regulation requiring 

stamping of the Coast Guard Symbol. 

The requirement for use of the Coast 

Guard Symbol on pressure vessels is 

often misunderstood. 

Modifying paragraph (b) to identify 

when shop inspection is required. Part 

54 refers to shop inspection of pressure 

vessels under construction in several 

locations, but the term is not used here. 

Adding new paragraph (c), 

redesignating existing paragraph (c) as 

new paragraph (d), and removing the 

requirement for stamping with the Coast 

Guard Symbol. The requirement for use 

of the Coast Guard Symbol on pressure 

vessels is often misunderstood. By 

applying the symbol, the marine 

inspector is documenting that the 

pressure vessel meets Coast Guard 

requirements for pressure vessels on 

ships. Adding a paragraph clarifies 

which pressure vessels do not require 

stamping. 

Section 54.10–20 Marking and 

Stamping 

Modifying paragraph (a)(2) to clarify 

numbering requirements. The 

requirement for Coast Guard numbering 

of pressure vessels is often 

misunderstood. Numbering is only 

required when the Coast Guard has 

inspected the pressure vessel during 

construction (shop inspection). 

Part 56—Piping Systems and 

Appurtenances 

Section 56.07–5 Definitions 

Clarifying the definition for ‘‘piping 

schedule’’ and deleting the definition 

for ‘‘plate flange,’’ as it does not require 

a definition. 

Section 56.07–10 Design Conditions 

and Criteria (Modifies 101–104.7) 

Modifying paragraph (b) by deleting 

the last sentence within the parentheses. 

It is not necessary to refer to definitions 

in part 52 for this paragraph. 

Modifying paragraph (d) by deleting 

text that was inadvertently repeated. 

Modifying paragraph (e) by removing 

references to specific paragraphs and 

instead referring to the entire subpart. 

Section 56.15–1 Pipe Joint Fittings 

Removing text in paragraph (c)(2) that 

is already adequately addressed by the 

incorporated ASME industry standard. 

Section 56.15–5 Fluid-Conditioner 

Fittings 

Deleting text in paragraph (c), 

nonstandard fluid conditioner fittings, 

that is already adequately addressed by 

paragraph (b); generally, fluid 

conditioner fittings must meet the 

requirements of this section regardless 

of whether they are ‘standard’ or 

‘nonstandard’, and must be appropriate 

for the fluid contained, and the 

temperature and pressure of the system. 

In addition, with advancements in 

manufacturing, there is no need to 

reference part 54 (pressure vessels), for 

fluid conditioner fittings in current 

paragraphs (c) and (d). 

Section 56.20–1 General 

Removing text that is redundant and 

that can be adequately replaced by the 

incorporated ASME standard. 

Section 56.20–9 Valve Construction 

Modifying paragraphs (a), (b), (c), (e), 

and (g) to reflect advancements in valve 

design technology and to remove text 

adequately addressed already by the 

incorporated ASME standard.

Resilient Material 

Deleting text that is no longer 

required and simplifying text to reflect 

current policy employed by the MSC to 

evaluate these types of valves. Overall, 

these valves are not required anywhere 

on ships, and this section only

Deleting the requirement in paragraph 

(a) that gas-consuming appliances be ‘‘of 

a type approved’’ by the Commandant. 

The requirement that the Commandant 

specifically ‘‘approve’’ all types of gasconsuming appliances is not necessary, 

given that appliances must already be 

tested and listed by third party 

laboratories and meet the additional 

requirements of Subpart 58.16. 

Changing the word ‘‘approved’’ to 

‘‘accepted’’ in paragraph (c). Because 

this paragraph refers to another 

government agency’s requirements for 

safety-relief devices, and shipboard 

appliance installations are reviewed 

case by case, ‘‘acceptance’’ allows for

64 and is summarized in section IV.B of 

this preamble. For information about 

how to view this material, see the 

ADDRESSES section of this preamble. 

Copies of the material are also available

50, 52, 53, 54, 56, 57, 58, 59, 61, 62, 63, 

and 64. Before publishing a binding 

rule, we will submit this material to the 

Director of the Federal Register for 

approval of the incorporation by 

reference. 

VI. Regulatory Analyses 

We developed this proposed rule after 

considering numerous statutes and 

Executive Orders related to rulemaking. 

A summary of our analyses based on 

these statutes or Executive Orders 

follows. 

A. Regulatory Planning and Review 

Executive Orders 12866 (Regulatory 

Planning and Review) and 13563 

(Improving Regulation and Regulatory 

Review) direct agencies to assess the 

costs and benefits of available regulatory 

alternatives and, if regulation is 

necessary, to select regulatory 

approaches that maximize net benefits 

(including potential economic, 

environmental, public health and safety 

effects, distributive impacts, and 

equity). Executive Order 13563 

emphasizes the importance of 

quantifying costs and benefits, reducing 

costs, harmonizing rules, and promoting 

flexibility. 

The Office of Management and Budget 

(OMB) has not designated this proposed 

rule a significant regulatory action 

under section 3(f) of Executive Order 

12866. Accordingly, OMB has not 

reviewed it. 

The Coast Guard proposes to update 

subchapter F of Title 46 of the CFR. This 

proposed rule would align the standards 

on U.S.-flagged vessels of vessel types of 

subchapter F with current industry 

practices to ensure that regulatory 

standards are current, and the changes 

would harmonize regulatory 

requirements with current industry 

standards. The majority of the updates 

simply would incorporate by reference 

the more recent versions of the same 

standards with little or no substantive 


jspears on DSK121TN23PROD with PROPOSALS2
Federal Register / Vol. 86, No. 199 / Tuesday, October 19, 2021 / Proposed Rules 57917 

2The proposed rule would continue the Coast 

Guard’s response to the Presidential Regulatory 

Reform Imitative of March 4, 1995, and directives 

including Executive Orders 12866 and 13563 that 

are intended to improve regulation and the 

regulatory process. The provisions of this proposed 

rule would remove outdated regulations, revise 

current regulatory text, and incorporate by reference 

more recent national and international industry 

standards into the CFR. The Coast Guard recognizes 

the significant technological advances technology 

and equipment which is used or carried on vessels. 

As a result, this proposed rule would encourage the 

use of newer equipment and promote adherence to 

modern standards in the industry. 

3Class societies and vessel insurers may have 

interest in the rule. However, no actions are 

required by them directly or indirectly as a result 

of the rule. 

4Public vessels are excluded. 

5Based on input from Coast Guard subject matter 

experts in the Directorate of Commercial 

Regulations and Standards who are tasked with 

relevant duties. 

change. In some cases, the more recent 

editions reflect more modern 

technologies, terminology, and 

practices. The updates also would 

correct regulatory language and remove 

redundant and outdated references. The 

Coast Guard believes there are no 

additional costs associated with this 

proposed rule. The Coast Guard 

estimates this rule will save the 

regulated public and federal government 

approximately $9.787 million over the 

10-year period of analysis at 7% in 2020 

dollars. 

The following regulatory analysis 

(RA) provides an evaluation of the 

economic impacts associated with this 

proposed rule. Table 2 provides a 

summary of the proposed rule’s costs 

and benefits. 

TABLE 2—SUMMARY OF THE PROPOSED RULE’S IMPACTS

Category Summary 

Affected Population ................................. Vessel owners and operators, shipyards, builders and manufacturers of vessels and vessel components, the Coast Guard (Marine Safety Center (MSC) and United States Coast Guard Commercial 

Regulations and Standards Directorate (CG–5PS)). Class societies and vessel insurers may have 

some interest. 

Costs ........................................................ None. The proposed rule would not increase costs of compliance for the regulated public or the 

Coast Guard because no additional requirements are being proposed. 

Cost Savings (7-percent discount rate) ... $9.787 million (10-year discounted cost savings), annualized cost savings: $1.385 million in 2020 dollars. 

Unquantified Benefits .............................. Clarity of regulatory intent through stylistic changes and corrections, harmonization of regulatory requirements with current industry standards, better utilization of Coast Guard human resources, 

compliance with Presidential Regulatory Reform Initiative (March 4, 1995).2

This proposed rule has two main 

goals. First, the Coast Guard intends it 

to update design standards that appear 

in the CFR by incorporating by reference 

more recent industry standards. Second, 

the proposed rule would provide clarity 

and simplify regulatory compliance for 

industry by removing obsolete 

regulations and revising current 

regulatory text, including the correction 

of errors. 

Affected Population 

The Coast Guard analyzed this 

rulemaking to determine the affected 

population and how the proposed rule 

would impact vessel owners and 

manufacturers.3 The proposed revisions 

affect a variety of vessel owners and 

operators; including those owning cargo 

vessels, passenger vessels, nautical 

school vessels, tank vessels, and tank 

barges. Some potentially impacted 

vessel owners and operators include 

nonprofits and Tribal/State/local 

government entities.4 Because the 

proposal impacts only new vessels or 

those undergoing major conversions, the 

Coast Guard estimates that fewer than 

200 vessels would be impacted 

annually.5

An estimated 16,148 vessels owned 

by 6,437 owners and operators would be 

impacted potentially, but the vessel 

owners and operators would be 

impacted directly only if they procured 

a new vessel or engaged in a major 

conversion of an existing vessel under 

conditions as specified in the proposal. 

Large self-propelled vessels, which are 

covered by more provisions of 

Subchapter F than smaller vessels and 

barges, would be more likely to be 

impacted. The following table details 

those vessels potentially impacted by 

the proposed rule.

complete accounting of affected paragraphs, 

including redesignations. 

7This list is not exhaustive. Please see Table 1 for 

the full list. 

8Please see Table 1 for complete list. 

9The proposed change would give operators the 

option of undergoing an internal inspection every 

10 years as opposed to requiring a hydrostatic test 

every 10 years. 

10UL 1111 has been withdrawn and no longer 

exists; therefore, it can no longer be included as an 

option for regulation compliance. 

The proposed rule also would impact 

businesses involved in vessel 

manufacturing. There are approximately 

1,022 shipyards and manufacturers of 

vessels or vessel components in the 

affected population; however, vessel 

manufacturers are believed to already be 

in voluntary compliance with the 

proposed changes. In addition, the 

proposal would impact the Coast Guard 

and its staff in the MSC and CG–5PS. 

An estimated six civilian engineers and 

six uniformed personnel potentially 

would be impacted. 

Summary of Changes 

Generally, the Coast Guard proposes 

to update codified references to 

standards incorporated by reference in 

subchapter F with their more recent 

editions. These more recent standards 

would provide more clarity and 

specificity than the outdated standards 

they would be replacing. More 

specifically, the Coast Guard segments 

the effect of the proposed changes into 

three categories: (1) Editorial changes to 

the CFR; (2) technical updates to 

standards incorporated by reference; 

and (3) compliance alternatives to 

standards incorporated by reference. 

Based on data from industry, the Coast 

Guard assumes industry already uses 

the more recent standards referenced in 

the proposal. Table 4 summarizes the 

regulatory changes. 

First, for the proposed changes to 

update standards incorporated by 

reference, this proposed rule would 

make editorial changes to subchapter F 

that include such items as the removal 

of outdated terminology and the 

consolidation of text. These proposed 

changes would include 46 CFR parts 50, 

52, 53, 54, 56, 57, 58, 59, 61, 62, 63 and 

64. The Coast Guard expects these 

changes would have no costs, cost 

savings, or benefits. 

Second, this proposed rule updates 

standards incorporated by reference 

throughout subchapter F. Because no 

resources are required, and because they 

have been adopted voluntarily already 

by manufacturers, the Coast Guard 

expects these changes would have no 

cost. 

Third, this proposed rule would 

amend the regulatory text in 46 CFR 

58.10–5(d)(1) and 61.10–5(g) that 

impacts compliance alternatives for 

vessel owners and operators. The 

changes reflect the proposed addition of 

a compliance alternative and the 

proposed removal of a compliance 

alternative. This proposed change 

results from the discontinuation of a 

standard incorporated by reference that 

is the basis of the compliance 

alternative. (Please see the preamble in 

the proposed changes to ‘‘Part 61— 

Periodic Tests and Inspections,’’ and 

further detailed in the Cost Savings 

portion of this RA.) These proposed 

changes provide regulatory flexibility 

for the regulated public. No additional 

cost would be incurred, and the 

addition of a compliance alternative 

may save money. The proposed rule’s 

replacement of a compliance alternative 

would offer an option which has lower 

costs associated with it. This would be 

a cost savings for vessel owners if they 

choose to use this compliance 

alternative. 

The proposed rule would create 

consistency between Coast Guard 

regulations and national and 

international standards through 

incorporation by reference, provide 

options with alternative standards, 

eliminate obsolete standards, and clarify 

the existing requirements through the 

changes proposed in 46 CFR subchapter 

F. Table 4 lists these proposed changes 

by type of change. Readers may consult 

the preamble of this NPRM for a general 

summary of the proposed changes.

offer flexibility for regulatory compliance which ultimately 

could save money for the vessel owner. 

Removal of compliance alternatives.§§ 56.50, 58.10–5(d)(1) 10 ..................................................... No cost or cost savings. The proposed change simplifies 

regulatory text to remove reference to a no longer existing IBR document and, by default, its availability as a 

compliance alternative. 

Note: The Coast Guard may list the same citation of the CFR multiple times because it is proposing numerous changes to the same paragraph. These changes 

may include clarifications, deletions, or insertions of text. 

Data Input for Calculations 

This RA uses multiple data sources. 

To estimate the duration of tasks, the 

Coast Guard used previous OMBapproved collections of information. 

These collections of information were 

previously vetted publicly and provide 

guidance on estimates of tasks such as 

communicating information and 

education. The RA also uses estimates 

from Coast Guard subject matter experts.

13A loaded hourly wage rate is what a company 

pays per hour to employ a person, not the hourly 

wage an employee receives. The loaded hourly 

wage rate includes the cost of non-wage benefits 

(health insurance, vacation, etc.). 

14To estimate the load factor, the Coast Guard 

used publicly available BLS data (https://

www.bls.gov/data/). To recreate these calculations, 

go to the ‘‘Databases, Tables & Calculators’’ page, 

select the multi-screen data search feature for 

‘‘Employer Costs for Employee Compensation’’ 

under ‘‘Pay & Benefits.’’ (Alternatively, a direct link 

can also be found at https://data.bls.gov/cgi-bin/ 

dsrv?cm.) For total compensation, in the search 

field select ‘‘Private industry workers,’’ then ‘‘Total 

compensation,’’ ‘‘Transportation and material 

moving occupations,’’ ‘‘All workers,’’ ‘‘All 

workers,’’ ‘‘United States (National),’’ ‘‘Cost of 

compensation (Cost per hour worked),’’ and ‘‘Not 

Seasonally Adjusted.’’ For wages and salaries, 

perform the same steps except select ‘‘Wages and 

salaries’’ on the second screen. The series IDs for 

total compensation and wages and salaries are 

CMU2010000520000D and CMU2020000520000D, 

respectively. Using fourth quarter data for 2020, the 

Coast Guard divided the value for total 

compensation, $31.76, by wages and salaries, 

$21.35, to estimate a load factor of approximately 

1.49 (rounded to the nearest tenth). Unrounded 

figures were used in calculations. 

15Based on data from the Congressional Budget 

Office (https://www.cbo.gov/system/files/115thcongress-2017-2018/reports/52637- 

federalprivatepay.pdf). The report provided 

estimates for total compensation for Federal 

workers at this educational level to be $51.90 per 

hour with wages of $29.70 per hour, in 2015 

dollars. The estimated load factor comports with 

later data as reported by BLS (see further for 

details). Unrounded figures were used in 

calculations.

November 17, 2020. The load factor is found by 

taking the quotient of compensation to benefits as 

found on Table 2 and 3 of the report. Coast Guard 

used the figures for Federal workers with 

professional degree or doctorate. To verify the 

accuracy of this load factor estimate, the Coast 

Guard compared it with findings from an analysis 

of BLS total compensation and wage data. The load 

factor comports with the data analysis of BLS 

Employer Costs for Employee Compensation, All 

workers in Public Administration. The load factor 

was obtained from https://www.bls.gov/web/ecec/ 

ececqrtn.pdf using Table 8 for public administration 

workers (4th Quarter 2020 data). The Coast Guard 

divided the value for total compensation, $51.54 by 

wages and salaries, or $29.54, to obtain a load factor 

of approximately 1.74 (rounded to the nearest 

tenth). Unrounded figures were used in 

calculations. 

19Some tasks may take less time in the future due 

to technological advances. However, the Coast 

Guard has assumed no change in duration of tasks 

over the period of annualization.

oes172121.htm. 

21See https://www.bls.gov/oes/2020/may/ 

oes113051.htm. 

To calculate wage rates, the Coast 

Guard used two publicly available 

sources for wage data: the U.S. 

Department of Labor Bureau of Labor 

Statistics (BLS) Occupational 

Employment Statistics and the 

Commandant Instruction entitled 

‘‘Reimbursable Standard Rates’’ 

(commonly called Commandant 

Instruction U).11 For positions outside 

the Coast Guard, the Coast Guard used 

publicly available data of the BLS 

Occupational Compensation Survey to 

estimate wage rates for positions that 

would be impacted by the proposed 

rule. For Coast Guard positions, the 

Coast Guard used publicly available and 

publicly vetted information found in 

Commandant Instruction U and the U.S. 

Office of Personnel Management pay 

chart for the Washington, DC locality 

pay area for 2020 12 to estimate the wage 

data. 

From the wage data obtained in the 

previous step, the Coast Guard used a 

loaded labor rate 13 to estimate the 

actual cost of labor to employers. The 

load factor (or benefits multipliers) for 

the regulated public and Coast Guard 

civilian workers was obtained using 

BLS data. To account for an employee’s 

non-wage benefits, the Coast Guard 

applied a load factor to the unloaded 

mean hourly wage rate; data of the 

BLS’s ‘‘Employer Cost for Employee 

Compensation’’ database were used for 

the regulated public’s wages.14 The 

Coast Guard determined the load factor 

to be about 1.49, rounded. For Coast 

Guard civilian positions, the load factor 

was determined to be approximately 

1.75, rounded.15 For Coast Guard 

uniformed positions, the Coast Guard 

used data that already had applied the 

load factor, so such an adjustment was 

not necessary.16 These figures were used 

to estimate the reasonable and 

customary average labor cost to 

employers. Table 5 displays the labor 

categories, the source of the wage rates, 

the total compensation, the wage rates, 

and the calculated load factor. We 

estimated the load factor for the 

applicable occupation category by 

dividing the total compensation by the 

hourly wage rate.

The Coast Guard assumed a constant

Likewise, the estimates are based on 

2020 dollars. Table 6 presents the 

estimated hourly loaded wage rates for 

the proposed rule.

(occupational code 17–2121) is 

$47.88.20 The Coast Guard multiplied 

$47.88 by the load factor of 1.49 to 

obtain a loaded mean hourly wage rate 

of about $71.23 for this occupation. The 

hourly rate for a manager (occupational 

code 11–3051) 21 of $56.82 was 

estimated to be $84.52 after the load 

factor application.

Costs 

The Coast Guard estimates there are 

no costs associated with this proposed 

rule. The proposed rule does not require 

actions of manufacturers or vessel 

owners and operators. The proposal is 

not retroactive, and existing vessels are 

not required to be retrofitted. 

This proposed rule would not require 

owners and operators to acquire any 

standards incorporated by reference; 

they would not need the standard in 

hand to be in compliance. Owners and 

operators only would need to look for 

evidence from manufacturers that 

vessels meet or exceed the standard 

before purchase; such evidence could be 

found in a contract for purchase or 

repair of a vessel or in product 

documentation such as a user guide or 

warranty information. For these reasons, 

the Coast Guard has not included a cost 

for the procurement of the newer 

standards for vessel owners. 

The Coast Guard estimates that the 

regulated public (manufacturers) are 

currently in voluntary compliance with 

the requirements proposed by the rule 

based on manufacturer participation in 

the development of industry standards. 

When industry standards are 

promulgated, they undergo a process of 

review and comment by the industry. 

Input from manufacturers is key to 

developing new standards that consider 

the engineering capabilities of 

manufacturers. After the review and 

comment process, the newer standard is 

voted upon at the various governing 

bodies’ committee meetings, and 

manufacturers are among those voting. 

For this reason, the Coast Guard

32A similar rulemaking is the proposed rule 

Revision of Crane Regulation Standards for Mobile 

Offshore Drilling Units, Offshore Supply Vessels, 

and Floating Outer Continental Shelf Facilities 

(Docket Number: USCG–2011–0992). Please see 

https://www.federalregister.gov/documents/2013/ 

05/13/2013-11132/revision-of-crane-regulationstandards-for-mobile-offshore-drilling-units-modusoffshore-supply (78 FR 27913). 

33The cost to acquire an IBR standard would be 

estimated by the equation (0.25 hour × supv wage 

rate + 0.5 hour × admin assistant wage rate + cost 

of IBR + shipping cost). This is based on the 

publicly vetted cost estimation found in the 

regulatory analysis for the proposed rule Revision 

of Crane Regulation Standards for Mobile Offshore 

Drilling Units, Offshore Supply Vessels, and 

Floating Outer Continental Shelf Facilities (Docket 

Number: USCG–2011–0992). 

34 If the owner or operator does not have staff 

sufficiently skilled to prepare the material, he or 

she may contract the services of an engineering 

design firm for the labor of a marine engineer or 

naval architect. The Coast Guard did not attempt to 

estimate the additional labor needed to engage 

contracted labor since it is unknown how many or 

even if an owner or operator would need outside 

labor to perform this task. Public comment is 

solicited on this. 

35The SBA rule is entitled Regulatory Reform 

Initiative: Small Disadvantaged Businesses, 

(Document Number: SBA 2020–08619) which was 

published on May 8, 2020. See https://

www.federalregister.gov/documents/2020/05/08/ 

2020-08619/regulatory-reform-initiative-smalldisadvantaged-businesses (85 FR 27290). 

believes manufacturers are aware and 

knowledgeable about the newer 

standards. Given this, we further 

assume they already would own copies 

of the standards. For this reason, the 

Coast Guard has not computed a cost for 

them to procure the standards 

incorporated by reference. The Coast 

Guard requests public comment on our 

assumption of voluntary compliance 

with the proposed rule. 

Manufacturers already have been 

producing equipment to meet the 

standard and typically will begin to 

make manufacturing modifications even 

before such changes are adopted 

formally. Therefore, the Coast Guard 

does not anticipate that there would be 

costs to retrofit manufacturing 

equipment to be in compliance with the 

proposed rule. For previous similar 

rulemakings, no manufacturer 

commented that it would experience 

incremental costs of production to 

comply with newer editions of 

standards incorporated by reference.32

For these reasons, the Coast Guard has 

not included a cost for these provisions. 

However, the Coast Guard 

acknowledges that there is a non-zero 

probability that some manufacturer may 

need to purchase a newer standard. The 

estimated incremental cost to do so 

varies according to which standard is 

needed.33

Cost Savings to the Regulated Public 

The proposal would result in cost 

savings to the regulated public and the 

Coast Guard from a reduction in labor 

for processing equivalency tests and no 

longer requiring labor to have education 

on the older standards incorporated by 

reference. The Coast Guard expects this 

proposed rule would generate cost 

savings for owners and operators who 

no longer would need to request a 

waiver of subchapter F regulatory 

requirements, known as an equivalency 

test request, from the MSC. 

Generally, the reason an owner or 

operator makes an equivalency request 

is to seek a determination from the 

Coast Guard on whether an edition of an 

industry standard not codified in the 

CFR is sufficient for use. To draft an 

equivalency request, an owner or 

operator would have material prepared 

by its engineering staff or by a 

contracted engineering firm.34

Based on MSC and CG–5PS data, the 

Coast Guard receives approximately 200 

equivalency requests annually. The 

Coast Guard estimates it takes a marine 

engineer or naval architect employed by 

a vessel owner approximately 40 hours 

of time to develop an equivalency 

request and submit it to the Coast Guard 

for review. An estimated 0.5 hour would 

be used by a supervisor engineer to 

approve the work. The request for an 

equivalency test is sent via email to the 

MSC. Given that the submittal is via 

email, the Coast Guard has not 

estimated postage costs. 

In addition, the regulated public 

would realize cost savings from the 

avoided cost of education for 

maintaining situational awareness on 

the existing standards incorporated by 

reference which the proposal would 

eliminate. The Coast Guard estimates 

that 0.5 hour is spent annually by 

engineers on education necessary to 

familiarize or re-familiarize themselves 

with these standards. The Coast Guard 

believes that, as industry standards 

evolve and advance, older editions may 

not be readily accessible, even if they 

are incorporated by reference into the 

CFR. As such, we expect that engineers 

will find the older standards and read 

them on occasion to maintain an 

awareness of how these standards are 

different from current industry 

standards. 

In 2020, the Small Business 

Administration (SBA) published a rule 

where it determined that roughly 2,500 

small disadvantaged businesses would 

save 0.5 hours each by no longer having 

to read 16 outdated regulations that SBA 

was removing through the rulemaking 

project.35 Given that this proposed rule 

relates to a similar subject matter—time 

saved from the removal of outdated or 

redundant regulations—the Coast Guard 

assumes a similar duration would be 

saved by industry employees. This 0.5 

hour is a savings to vessel owners and 

operators and to manufacturers. 

Cost Savings to the Coast Guard 

The Coast Guard also would 

experience cost savings as a result of the 

proposed rule. When the Coast Guard 

receives an equivalency request from a 

vessel owner or operator, a Coast Guard 

engineering staff member at the MSC 

must review the request to provide a 

determination on whether the proposed 

standard(s) is equivalent to the existing 

standard(s) found in subchapter F. The 

Coast Guard MSC engineer needs 

approximately 32 hours to review an 

equivalency request, followed by 0.5 

hours of supervisor review. In a small 

percentage of more complex cases, the 

MSC works with CG–5PS engineering 

staff to complete the equivalency 

review. Following review, MSC emails a 

decision back to the owner or operator. 

The Coast Guard estimates it reviews 

200 equivalency requests annually. To 

calculate the costs avoided by Coast 

Guard no longer processing equivalency 

requests, we multiplied the number of 

annual equivalency requests by the sum 

of the duration of initial review, review, 

and supervisor review multiplied by the 

loaded wage rates of the respective 

Coast Guard personnel performing the 

review (200 equivalency requests × (1 

hour × average wage rate for uniformed 

engineer + 32 hours × wage rate for 

civilian engineer + 0.5 hours × wage rate 

for civilian engineering supervisor)). 

In addition, the Coast Guard would 

save labor costs annually, since staff 

would no longer need to maintain an 

awareness of the older versions of 

standards that are incorporated by 

reference. The proposal eliminates and 

replaces them with newer standards. 

The Coast Guard estimates that 0.5 hour 

annually is spent on education on the 

older standards by an employee tasked 

with working on equivalency requests. 

In the aforementioned SBA proposed 

rule, the agency claimed that about 760 

Federal contracting officers per year 

would save 0.5 hours from no longer 

reading outdated standards that were 

being removed by the rule. We therefore 

estimate 0.5 hours of education is 

similarly needed for Coast Guard 

personnel to maintain awareness and 

knowledge of older standards. This 

applies to six civilian engineers and six 

uniformed engineers who work on 

equivalency requests. To calculate the 

costs avoided by Coast Guard personnel 

no longer requiring education on 

outdated standards, we multiply 0.5 

hours by the hourly wage rates of the

36Existing regulations have been misunderstood 

as to whether a pressure vessel (PV) requires or 

does not require plan review by the Coast Guard. 

This proposed change clarifies regulatory intent and 

would preclude inquiries to the Coast Guard. 

37The requirement for Coast Guard numbering of 

PVs is misunderstood often. The proposed change 

clarifies that Coast Guard numbering is required 

only when the Coast Guard has inspected the PV 

during construction (shop inspection). 

38The requirement for use of the Coast Guard 

Symbol on PVs (§ 54.10–3) often is misunderstood.

41This information would be needed to ascertain 

the existing cost of compliance; the Coast Guard 

could then estimate the cost savings of the proposed 

new compliance alternative. 

42The proposed adoption of the newer editions 

would mean that some outdated requirements of the 

earlier editions are no longer required or are 

converted to recommendations rather than 

requirements. The newer editions also include 

some flexibility in requirements and 

recommendations based on the given 

circumstances. The reader may consult the 

appendix for a detailed analysis of the changes 

between the editions.

Note: Totals may not sum due to independent rounding. 

The Coast Guard estimates an 

annualized cost savings to industry of 

$0.622 million (with a 7-percent 

discount rate) and an annualized cost 

savings to Government of $0.772 million 

(with a 7-percent discount rate) for a 

total annualized cost savings of $1.393 

million in 2020 dollars. 

Cost Savings 

The proposed rule amends existing 

regulations in 46 CFR subchapter F. The 

proposed amendments would eliminate 

confusion caused by outdated and 

conflicting rules on marine engineering 

safety of various vessel components and 

systems and give the maritime industry 

clear instructions on how to comply 

with regulations. Moreover, this 

proposed rule would amend existing 

regulations to reflect current national 

and international standards. The 

proposed rule also would result in cost 

savings to the regulated public and the 

Federal Government, as noted further. 

Several of the proposed rule’s changes 

have no cost effects (please see Table 4). 

These editorial changes, such as the 

removal of outdated terminology and 

the consolidation of text, would not 

result in cost savings but would clarify 

regulations, as noted earlier. Also, by 

incorporating the newer standards, the 

proposed changes would provide clarity 

and specificity. For these changes, the 

Coast Guard expects them to have no 

direct cost savings because they are 

unseverable from the cost savings noted 

previously. 

The compliance alternatives would 

remove overly prescriptive 

requirements, simplify regulatory 

compliance, and provide regulatory 

flexibility for industry. The proposal 

would add a compliance alternative to 

hydrostatic tests, thereby allowing the 

regulated public to perform an internal 

inspection in lieu of the hydrostatic test. 

The proposed inclusion of this 

compliance alternative would save a 

given vessel owner labor and material. 

In order to comply with the existing 

requirement for hydrostatic tests, the 

vessel owner must remove existing 

lagging around the unit, then replace it 

once the test is completed. The 

proposed compliance alternative would 

involve less labor and would not 

necessitate the removal and replacement 

of lagging as the existing requirements 

do. The Coast Guard has not estimated 

a cost for this alternative, because it is 

unknown how many vessel owners 

would choose to pursue the alternative. 

Because equipment sizes vary, the 

amount of labor and material needed to 

comply now and under the alternative 

is also unknown.41 The Coast Guard 

invites public comment on this issue. 

Alternatives Considered 

Within the Coast Guard’s 

development of this proposed rule, 

significant alternatives to the regulatory 

component(s) were considered to 

determine if any alternative could 

accomplish the stated objectives of 

applicable statutes and could minimize 

any significant economic impact of the 

rule on small entities beyond the 

proposed rule. Among these alternatives 

were the following: 

Alternative 1: Take No Action 

The Coast Guard could have chosen 

not to pursue the rulemaking. Taking no 

action would cause no incremental costs 

to regulated entities nor to the Coast 

Guard. However, in doing nothing, the 

Coast Guard would have no mechanism 

to update regulations to reflect current 

practices and improve their relevance to 

the public. There would be neither an 

increase nor decrease in benefits to 

regulated entities due to the alternative. 

The proposed rule has been estimated to 

produce quantifiable cost savings to the 

Coast Guard and the regulated public, 

which would not be possible under the 

alternative of no action. 

The standards currently incorporated 

by reference are outdated. To keep them 

codified would, in theory, maintain 

existing safety levels. However, because 

they are so outdated, they are sparsely 

available. Compliance with them may 

become problematic in the future due to 

lack of availability. The older editions of 

the standards do not contain guidance 

for several current industry practices. 

Maintaining the regulations with the 

existing standards incorporated by 

reference would not allow for cost 

savings as the proposal would do. 

The goal of this proposed rule is to 

streamline requirements, to clarify 

existing rules and to increase 

enforcement effectiveness. The noaction alternative would result in no 

additional costs and maintain current 

levels of public safety. Similarly, the 

proposed rule is anticipated to have cost 

savings opportunities; 42 and these 

savings would not accrue to the public 

if current regulations were not 

amended. The proposed rule also is 

being promulgated to provide clarity on 

regulatory intentions; a no-action choice 

would not permit this clarification to be 

given to the public. This alternative 

would result in no benefits as there 

would be no changes to current practice; 

therefore, the Coast Guard rejected this 

alternative.

57924 Federal Register / Vol. 86, No. 199 / Tuesday, October 19, 2021 / Proposed Rules 

43The Regulatory Flexibility Act considers the 

term ‘‘small entity’’ as having the same meaning as 

the terms ‘‘small business,’’ ‘‘small organization’’ 

and ‘‘small governmental jurisdiction.’’ 

44 42 U.S. Code 6939d(c)(1) provides, ‘‘The term 

‘public vessel’ means a vessel owned or bareboat 

chartered and operated by the United States or by 

a foreign nation, except when the vessel is engaged 

in commerce.’’ 

45The SBA threshold for a small entity is either 

the maximum number of employees or the 

maximum revenue level (or population size for a 

State/local government). Size standards may be 

found in 13 CFR 121.201. 

46The NAICS codes for the parent company may 

differ for its subsidiaries. 

47Separate samples were performed for managing 

owners that are governmental entities or nonprofits. 

48The Coast Guard used a sample size of 190 

(alpha = 0.10, confidence interval of 90%). 

49We found data on 81 percent of nonprofits that 

were managing owners and data for all 

governmental entities that were managing owners. 

50www.dnb.com and www.charitynavigator.org 

(for nonprofits). 

51https://www.sba.gov/document/support--tablesize-standards. 

52The following NAICS codes were found for 

most sampled owners (excluding governmental 

entities and nonprofits): 441222 Boat Dealers; 

237990 Other Heavy and Civil Engineering 

Construction; 325110 Petrochemical Manufacturing; 

336611 Ship Building and Repairing; 483111 Deep 

Sea Freight Transportation, 454310 Fuel Dealers, 

237310 Hwy, Street, and Bridge Construction; 

483211 Inland Water Freight Transportation; and 

488330 Navigational Services to Shipping. This list 

is not exclusive. 

53The most commonly found NAICS codes for 

nonprofits in the sample were 813410 Civic and 

Social Organizations; 611710 Educational Support 

Services; 813312 Environment, Conservation and 

Wildlife Organizations; and 712110 Museums. This 

list is not exclusive. 

Alternative 2: Delay the Effective Date 

The Coast Guard could have delayed 

the effective date. Delayed effective 

dates are used to aid in compliance 

implementation, particularly when the 

labor costs or capital costs are 

considerable. The compliance costs for 

the proposal are zero as noted earlier, 

and a delayed effective date would 

delay the cost savings opportunities to 

all parties. For these reasons, the Coast 

Guard rejected this alternative. 

Alternative 3. Exempt Small Entities 

The Coast Guard could have 

exempted small entities from some or 

all of the proposed rule’s provisions. In 

principle, an exemption would save 

small entities time and money to 

comply with regulations. Exemptions 

for small entities often are used when 

costs of compliance, such as capital 

costs, are high. However, there are no 

costs of compliance for this proposed 

rule. For this alternative, an exemption 

may cause the cost savings 

opportunities of the rulemaking to be 

precluded for small entities and, 

thereby, the total value of the rule’s cost 

savings would decline accordingly. 

The proposal would implement 

requirements for business practices in 

which the majority (if not all) of small 

businesses now engage. An exemption 

for small business entities from the 

rulemaking would have little effective 

and practical impact on small business 

entities. There is a high level of 

voluntary compliance and limited 

applicability for the affected population. 

The costs of compliance are zero and 

the rule is applicable only if an 

actionable event occurs (for example, if 

a new vessel is procured or an existing 

vessel undergoes a major conversion). 

For these reasons, the Coast Guard did 

not pursue an exemption for small 

entities. 

B. Small Entities 

The Regulatory Flexibility Act of 1980 

(RFA), 5 U.S.C. 601–612, and Executive 

Order 13272 (Consideration of Small 

Entities in Agency Rulemaking) requires 

a review of proposed and final rules to 

assess their impacts on small entities. 

An agency must prepare an initial 

regulatory flexibility analysis unless it 

determines and certifies that a rule, if 

promulgated, would not have a 

significant impact on a substantial 

number of small entities. 

Under the RFA, we have considered 

whether this proposed rule would have 

a significant economic impact on a 

substantial number of small entities. 

The term ‘‘small entities’’ 43 comprises 

small businesses, not-for-profit 

organizations that are independently 

owned and operated and are not 

dominant in their fields, and 

governmental jurisdictions with 

populations of less than 50,000. 

Based on our analysis, this proposed 

rule would affect vessel owners and 

operators, manufacturers and class 

societies. While the proposed rule 

excludes public vessels,44 there exists 

considerable diversity in the types of 

vessel owners that may be impacted by 

the proposal. Some vessel owners 

potentially impacted by this proposed 

rule include Tribal, State, and local 

governments as well as nonprofits 

including colleges and universities, 

museums, and science foundations. 

The MISLE database maintained by 

the Coast Guard contains detailed 

information on the U.S. maritime 

industry, including vessel and major 

equipment specific information, and 

MISLE data suggest that the potentially 

affected population contains thousands 

of vessels for thousands of vessel 

owners and operators. While there 

exists no exact figure of the population 

of U.S.-flagged vessels and their owners 

and operators, and the Coast Guard does 

not maintain a registry of all vessels, 

many vessels are documented and 

therefore there is a record of the owner. 

For these reasons, the Coast Guard was 

able to estimate the number of vessel 

owners and operators impacted by the 

proposed rulemaking based on the 

MISLE dataset of U.S.-flagged vessels. 

The Coast Guard used this dataset of 

vessels, refined to eliminate duplicate 

managing owner names, to create a 

dataset of unique owner names to serve 

as a proxy for the number of vessel 

owners in the affected population. 

The SBA uses either revenue level or 

employment size to establish small 

entity size categories.45 For that reason, 

the Coast Guard reviewed publicly 

available information to determine 

revenue and employment estimates. 

These sources included but were not 

limited to www.manta.com, 

www.dnb.com, and the corporate 

websites of several businesses. The 

reader should note that the Coast Guard 

used data for the governing body of a 

corporate entity. In other words, for 

affected business entities that were 

subsidiaries of another company; the 

employment size and revenue level of 

the parent company was compared to 

the small business size standard for the 

North American Industry Classification 

System (NAICS) code of the parent 

company.46

The Coast Guard used a random 

sample to estimate the number of small 

entities that are manufacturers and 

managing owners.47 The Coast Guard 

was able to find data on approximately 

92 percent of the sampled managing 

owner businesses and 88.6 percent of 

manufacturers impacted by the rule. 48 49

Publicly available data were used to 

obtain company-specific information 

such as annual revenues and number of 

employees.50 Any company for which 

the Coast Guard did not find data was 

considered small.51 Using the SBA’s 

‘‘Table of Size Standards’’ and the 

NAICS codes listed in the table, the 

Coast Guard found that 21.35 percent of 

governmental entities that were 

managing owners of vessels are small 

entities.52 For nonprofits, 84.48 percent 

were small entities.53 For the remaining 

companies owning vessels in the 

affected population, the Coast Guard 

found that 85.85 percent were small 

entities. For manufacturers, the Coast 

Guard estimates that 62.03 percent of 

companies were small entities. 

Cost savings are incurred only under 

conditions as specified in the proposal. 

The cost saving for each vessel owner or 

operator would be approximately $2,923 

per entity, which is less than 1 percent 


jspears on DSK121TN23PROD with PROPOSALS2
Federal Register / Vol. 86, No. 199 / Tuesday, October 19, 2021 / Proposed Rules 57925 

of revenue for 72.48 percent of small 

entity managing owners. These cost 

savings are incurred only if the 

regulated entity experienced tasks as 

noted in the proposed rule. For most 

vessel owners and operators, there 

would be no cost nor cost savings from 

the proposed rule. 

Therefore, the Coast Guard certifies 

under 5 U.S.C. 605(b) that this proposed 

rule would not have a significant 

economic impact on a substantial 

number of small entities. 

If you think that your business, 

organization, or governmental 

jurisdiction qualifies as a small entity 

and that this rule would have a 

significant economic impact on it, 

please submit a comment to docket at 

the address in the ADDRESSES section. In 

your comment, explain why you think 

it qualifies and how and to what degree 

this rule would affect it economically. 

C. Assistance for Small Entities 

Under section 213(a) of the Small 

Business Regulatory Enforcement 

Fairness Act of 1996, Public Law 104– 

121, we want to assist small entities in 

understanding this proposed rule so that 

they can better evaluate its effects on 

them and participate in the rulemaking. 

If the proposed rule would affect your 

small business, organization, or 

governmental jurisdiction and you have 

questions concerning its provisions or 

options for compliance, please call or 

email the person in the FOR FURTHER

INFORMATION CONTACT section of this 

proposed rule. The Coast Guard will not 

retaliate against small entities that 

question or complain about this 

proposed rule or any policy or action of 

the Coast Guard. 

Small businesses may send comments 

on the actions of Federal employees 

who enforce, or otherwise determine 

compliance with, Federal regulations to 

the Small Business and Agriculture 

Regulatory Enforcement Ombudsman 

and the Regional Small Business 

Regulatory Fairness Boards. The 

Ombudsman evaluates these actions 

annually and rates each agency’s 

responsiveness to small business. If you 

wish to comment on actions by 

employees of the Coast Guard, call 1– 

888–REG–FAIR (1–888–734–3247). 

D. Collection of Information 

This proposed rule would not require 

a modification of an existing collection 

of information (Plan Approval and 

Records for Marine Engineering 

Systems—Title 46 CFR Subchapter F 

OMB Control Number: 1625–0097) and 

would not call for new collection of 

information under the Paperwork 

Reduction Act of 1995 (PRA), 44 U.S.C. 

3501–3520. As defined in 5 CFR 

1320.3(c), ‘‘collection of information’’ 

comprises reporting, recordkeeping, 

monitoring, posting, labeling, and other 

similar actions. 

E. Federalism 

A rule has implications for federalism 

under Executive Order 13132 

(Federalism) if it has a substantial direct 

effect on the States, on the relationship 

between the national government and 

the States, or on the distribution of 

power and responsibilities among the 

various levels of government. We have 

analyzed this proposed rule under 

Executive Order 13132 and determined 

that it is consistent with the 

fundamental federalism principles and 

preemption requirements described in 

Executive Order 13132. Our analysis 

follows. 

It is well settled that States may not 

regulate in categories reserved by 

Congress for regulation by the Coast 

Guard. It is also well settled that all of 

the categories regulated under 46 U.S.C. 

3306 and 3703, as well as any other 

category in which Congress intended 

the Coast Guard to be the sole source of 

a vessel’s obligations, are within the 

field foreclosed from regulation by the 

States. See the Supreme Court’s 

decision in United States v. Locke and 

Intertanko v. Locke, 529 U.S. 89, 120 

S.Ct. 1135 (2000). This proposed 

rulemaking updates the references to 

incorporated standards in 46 CFR 

Subchapter F, which is authorized 

under 43 U.S.C. 1333, 46 U.S.C. 3306, 

and 46 U.S.C. 3703. Therefore, because 

the States may not regulate within these 

categories, this rule is consistent with 

the fundamental federalism principles 

and preemption requirements described 

in Executive Order 13132. 

While it is well settled that States may 

not regulate in categories in which 

Congress intended the Coast Guard to be 

the sole source of a vessel’s obligations, 

the Coast Guard recognizes the key role 

that State and local governments may 

have in making regulatory 

determinations. Additionally, for rules 

with federalism implications and 

preemptive effect, Executive Order 

13132 specifically directs agencies to 

consult with State and local 

governments during the rulemaking 

process. If you believe this proposed 

rule has implications for federalism 

under Executive Order 13132, please 

contact the person listed in the FOR

FURTHER INFORMATION section of this 

preamble. 

F. Unfunded Mandates Reform Act 

The Unfunded Mandates Reform Act 

of 1995, 2 U.S.C. 1531–1538, requires 

Federal agencies to assess the effects of 

their discretionary regulatory actions. In 

particular, the Act addresses actions 

that may result in the expenditure by a 

State, local, or tribal government, in the 

aggregate, or by the private sector of 

$100,000,000 (adjusted for inflation) or 

more in any one year. Although this 

proposed rule would not result in such 

an expenditure, we do discuss the 

effects of this proposed rule elsewhere 

in this preamble. 

G. Taking of Private Property 

This proposed rule would not cause a 

taking of private property or otherwise 

have taking implications under 

Executive Order 12630 (Governmental 

Actions and Interference with 

Constitutionally Protected Property 

Rights). 

H. Civil Justice Reform 

This proposed rule meets applicable 

standards in sections 3(a) and 3(b) (2) of 

Executive Order 12988, (Civil Justice 

Reform), to minimize litigation, 

eliminate ambiguity, and reduce 

burden. 

I. Protection of Children 

We have analyzed this proposed rule 

under Executive Order 13045 

(Protection of Children from 

Environmental Health Risks and Safety 

Risks). This proposed rule is not an 

economically significant rule and would 

not create an environmental risk to 

health or risk to safety that might 

disproportionately affect children. 

J. Indian Tribal Governments 

This proposed rule does not have 

Tribal implications under Executive 

Order 13175 (Consultation and 

Coordination with Indian Tribal 

Governments), because it would not 

have a substantial direct effect on one or 

more Tribal governments, on the 

relationship between the Federal 

Government and Tribal governments, or 

on the distribution of power and 

responsibilities between the Federal 

Government and Tribal governments. 

K. Energy Effects 

We have analyzed this proposed rule 

under Executive Order 13211 (Actions 

Concerning Regulations That 

Significantly Affect Energy Supply, 

Distribution, or Use). We have 

determined that it is not a ‘‘significant 

energy action’’ under that order because 

it is not a ‘‘significant regulatory action’’ 

under Executive Order 12866 and is not 

likely to have a significant adverse effect 

on the supply, distribution, or use of 

energy.

L. Technical Standards 

The National Technology Transfer 

and Advancement Act, codified as a 

note to 15 U.S.C. 272, directs agencies 

to use voluntary consensus standards in 

their regulatory activities unless the 

agency provides Congress, through 

OMB, with an explanation of why using 

these standards would be inconsistent 

with applicable law or otherwise 

impractical. Voluntary consensus 

standards are technical standards (such 

as for specifications of materials, 

performance, design, or operation; test 

methods; sampling procedures; and 

related management systems practices) 

that are developed or adopted by 

voluntary consensus standards bodies. 

This proposed rule uses the following 

voluntary standards:

M. Environment 

We have analyzed this proposed rule 

under Department of Homeland 

Security Management Directive 023–01, 

Rev. 1, associated implementing 

instructions, and Environmental 

Planning COMDTINST 5090.1 (series), 

which guide the Coast Guard in 

complying with the National 

Environmental Policy Act of 1969 (42 

U.S.C. 4321–4370f), and have made a 

preliminary determination that this 

action is one of a category of actions that 

do not individually or cumulatively 

have a significant effect on the human 

environment. A preliminary Record of 

Environmental Consideration 

supporting this determination is 

available in the docket. For instructions 

on locating the docket, see the 

ADDRESSES section of this preamble. 

This proposed rule would be 

categorically excluded under paragraphs 

L54, L57 and L58 of Appendix A, Table 

1 of DHS Instruction Manual 023–01, 

Rev. 1.54 Paragraph L54 pertains to 

regulations which are editorial and 

procedural; paragraph L57 pertains to 

regulations concerning manning, 

documentation, admeasurement, 

inspection, and equipping of vessels; 

and paragraph L58 pertains to 

regulations concerning equipment 

approval and carriage requirements. 

This proposed action involves 

amending rules relating to standards for 

marine engineering details for various 

types of vessels, including incorporation 

of national and international safety 

standards by reference. This proposed 

rule is part of the Coast Guard’s ongoing 

regulatory reform efforts to increase 

compliance options for the regulated 

public while providing cost savings to 

the public and U.S. Government, and 

also would promote the Coast Guard’s 

marine safety mission. We seek any 

comments or information that may lead 

to the discovery of a significant 

environmental impact from this 

proposed rule.

follows: 

§ 52.01–3. Definition of terms used in this 

part. 

For primary definitions associated 

with power boiler design, see Section I 

of the ASME BPVC (incorporated by 

reference; see § 52.01–1). 

(a) Types of boilers—(1) Main power 

boiler. A main power boiler is a steam 

boiler used for generating steam for 

main propulsion. 

(2) Auxiliary or donkey boiler. An 

auxiliary or donkey boiler is a steam 

boiler used for general purposes other 

than main propulsion. 

(3) Watertube boiler. A watertube 

boiler is a steam boiler in which the 

boiler tubes contain water and steam. 

The heat is applied to the outside 

surface of the tubes.

Federal Register / Vol. 86, No. 199 / Tuesday, October 19, 2021 / Proposed Rules 57931 

(4) Internally fired firetube boiler 

(scotch boiler). An internally fired 

firetube boiler is a steam boiler 

containing furnaces, one or more 

combustion chambers and tubes or 

flues, which are surrounded by water 

and through which the products of 

combustion pass from the furnace to the 

uptake. 

(5) Externally fired firetube or flue 

boiler (horizontal return tubular). An 

externally fired firetube or flue boiler is 

a steam boiler, part of the outer shell of 

which is exposed to fire or to the 

products of combustion, and containing 

flues through which such products pass 

from the furnace to the uptake. 

(6) Unfired steam boiler. A pressure 

vessel in which steam is generated by 

means other than fuel combustion is 

classed as an unfired steam boiler. (See 

§ 54.01–10 of this subchapter.) 

(b) Parts of boilers— (1) Superheater. 

A superheater is an appliance, normally 

consisting of tube rows, for the purpose 

of increasing the temperature of steam 

above the saturation temperature. 

(2) Economizer. An economizer is a 

feed-water heater usually located in the 

uptake or casing of a boiler to absorb 

heat from the waste gases. 

(3) Furnace. A furnace is a firebox or 

a large flue in which the fuel is burned. 

(4) Flues. Flues are cylindrical shells 

made of seamless or welded tubing, or 

with a riveted longitudinal joint, the 

ends being attached by riveting or 

welding. Their purpose is to provide 

additional heating surface and to form a 

path for the products of combustion. 

(5) Tubes. Tubes are cylindrical shells 

of comparatively small diameter 

constituting the main part of the heating 

surface of a boiler or superheater. 

(c) Pressure relief devices. For boilers, 

pressure vessels, and pressure piping, a 

pressure relief device is designed to 

open to prevent a rise of internal 

pressure in excess of a specified value 

due to emergency or abnormal 

conditions. It may be a pressure relief 

valve or a nonreclosing pressure relief 

device. 

(1) Pressure relief valve. A pressure 

relief valve is a pressure relief device 

which is designed to reclose and 

prevent the further flow of fluid after 

normal conditions have been restored. 

(i) Safety valve. A safety valve is a 

pressure relief valve actuated by inlet 

static pressure and characterized by 

rapid opening or pop action. Examples 

of types used on boilers include: 

(A) Spring-loaded safety valve. A 

spring-loaded safety valve is a safety 

valve fitted with a spring which 

normally holds the valve disk in a 

closed position against the seat and 

allows it to open or close at 

predetermined pressures. Spring-loaded 

safety valves are characterized by pop 

action. 

(ii) Pilot operated pressure relief 

valve. A pilot operated pressure relief 

valve is a pressure relief valve in which 

the major relieving device is combined 

with and is controlled by a self-actuated 

auxiliary pressure relief pilot valve. 

(iii) Temperature actuated pressure 

relief valve. A temperature actuated 

pressure relief valve is a dual-function 

relief device designed to protect against 

both excessive pressure and 

temperature. 

(2) Nonreclosing pressure relief 

device. A nonreclosing pressure relief 

device is a pressure relief device not 

designed to reclose after operation. 

(i) Rupture disk device. A rupture disk 

device is a device actuated by inlet 

static pressure and designed to function 

by the bursting of a pressure retaining 

disk. 

(ii) Explosion rupture disk device. An 

explosion rupture disk device is a 

rupture disk device designed for use at 

high rates of pressure rise. 

(iii) Fusible plug device. A fusible 

plug device is a device designed to 

function by the yielding or melting of a 

plug of suitable melting temperature. 

(3) Vacuum relief valve. A vacuum 

relief valve is a valve designed to admit 

fluid or gas to prevent an excessive 

internal vacuum. 

(d) Other boiler attachments—(1) 

Mountings. Mountings are nozzle 

connections, distance pieces, valves, or 

fittings attached directly to the boiler. 

(2) Main steam stop valve. A main 

steam stop valve is a valve usually 

connected directly to the boiler for the 

purpose of shutting off the steam to/ 

from the main steam line. 

(3) Auxiliary steam stop valve. An 

auxiliary steam stop valve is a valve 

usually connected directly to the boiler 

for the purpose of shutting off the steam 

to/from the auxiliary lines. 

(4) Manifold. A manifold is a fitting 

with two or more branches having 

valves either attached by bolting or 

integral with the fitting. 

(5) Blowoff valve. A blowoff valve is 

a valve connected directly to the boiler 

for the purpose of blowing out water, 

scum or sediment. 

(6) Dry pipe. A dry pipe is a 

perforated or slotted pipe placed in the 

highest part of the steam space of a 

boiler to prevent priming (water 

carryover). 

(7) Water column. A water column is 

a fitting or tube equipped with a water 

glass attached to a boiler for the purpose 

of indicating the water level. 

(8) Test cocks. Test cocks are small 

valves on a boiler for indicating the 

water level or water sampling. 

(9) Fusible plugs. Fusible plugs are 

plugs made with a bronze casing and a 

tin filling which melts at a temperature 

of 445° to 450 °F. They are intended to 

melt in the event of low water level. 

(e) Boiler fabrication—(1) Repair. 

Repair is the restoration of any damaged 

or impaired part to an effective and safe 

condition. 

(2) Alteration. Alteration is a 

structural modification to or departure 

from an approved design or existing 

construction. 

(3) Access or inspection openings. 

Access or inspection openings are holes 

cut in the shells or heads of boilers or 

boiler pressure parts for the purpose of 

inspection and cleaning. 

(f) Gage (or gauge) pressure. Gage 

pressure is the difference between the 

pressure at the point being measured 

and the ambient pressure for the gage. 

It is measured in units such as pounds 

per square inch gage (p.s.i.g.). 

(g) Maximum allowable working 

pressure. For a definition of maximum 

allowable working pressure, see PG–21 

of Section I of the ASME BPVC.

The revisions read as follows: 

§ 52.01–120 Safety valve and safety relief 

valves (modifies PG–67 through PG–73). 

(a) * * * 

(4) (Modifies PG–70.) The total rated 

relieving capacity of drum and 

superheater safety valves as certified by 

the valve manufacturer must not be less 

than the maximum generating capacity 

of the boiler which must be determined 

and certified by the boiler manufacturer. 

This capacity shall be in compliance 

with PG–70 of Section I of the ASME 

BPVC. 

(5) In the event the maximum steam 

generating capacity of the boiler is 

increased by any means, the relieving 

capacity of the safety valves must be 

checked by an inspector, and, if 

necessary, valves of increased relieving 

capacity must be installed. 

(6) (Modifies PG–67.) Drum safety 

valves must be set to relieve at a 

pressure not in excess of that allowed by 

the Certificate of Inspection. Where for 

any reason this is lower than the 

pressure for which the boiler was 

originally designed and the revised 

safety valve capacity cannot be 

recomputed and certified by the valve 

manufacturer, one of the tests described 

in PG–69 of section I of the ASME BPVC 

must be conducted in the presence of 

the Inspector to insure that the relieving 

capacity is sufficient at the lower 

pressure. 

* * * * * 

(8) Lever or weighted safety valves 

now installed may be continued in use 

and may be repaired, but when repairs 

are not possible, lever or weighted 

safety valves must be replaced by valves 

conforming to the requirements of this 

section. 

* * * * * 

(b)(1) (Modifies PG–68.) Superheater 

safety valves must be as indicated in 

PG–68 of Section I of the ASME BPVC 

except as noted otherwise in this 

paragraph. 

(2) The setting of the superheater 

safety valve must not exceed the design 

pressure of the superheater outlet flange 

or the main steam piping beyond the 

superheater. To prevent damage to the 

superheater, the drum safety valve must 

be set at a pressure not less than that of 

the superheater safety valve setting plus 

5 pounds, plus the pressure drop 

through the superheater and associated 

piping, including the desuperheater if 

fitted. See also § 52.01–95(b)(1). 

* * * * * 

(c)(1) (Modifies PG–71.) Safety valves 

must be installed as indicated in PG–71 

of Section I of the ASME BPVC except 

as noted otherwise in this paragraph (c). 

(2) The final setting of boiler safety 

valves must be checked and adjusted 

under steam pressure and, if possible, 

while the boiler is on line and at 

operating temperatures, to the 

satisfaction of a marine inspector who, 

upon acceptance, must seal the valves. 

This regulation applies to both drum 

and superheater safety valves of all 

boilers. 

(3) The safety valve body drains 

required by PG–71 of Section I of the 

ASME BPVC must be run as directly as 

possible from the body of each safety 

valve, or the drain from each safety 

valve may be led to an independent 

header common only to boiler safety 

valve drains. No valves of any type may 

be installed in the leakoff from drains or 

drain headers and they must be led to 

suitable locations to avoid hazard to 

personnel. 

(d)(1) (Modifies PG–72.) The operation 

of safety valves must be as indicated in 

PG–72 of Section I of the ASME BPVC 

except as noted in paragraph (d)(2) of 

this section. 

(2) (Modifies PG–73.) The lifting 

device required by PG–73.1.3 of Section 

I of the ASME BPVC must be fitted with 

suitable relieving gear so arranged that 

the controls may be operated from the 

fireroom or engineroom floor.

§ 54.05–5 Toughness test specimens. 

(a) Charpy V-notch impact tests. 

Where required, Charpy V-notch tests 

must be conducted in accordance with 

ASTM E23 (incorporated by reference, 

see § 54.01–1), using the Type A 

specimen shown in ASTM E23—Figure 

4. Special attention is drawn to the fact 

that the Charpy Keyhole and U-notch 

specimens are not acceptable substitutes 

for the Charpy V-notch specimen and 

must not be used to qualify materials 

within the scope of this subpart. Each 

set of Charpy impact tests must consist 

of three specimens. For materials 1⁄2- 

inch thick or less, the largest possible 

Charpy specimens for that thickness 

must be cut centered at the material’s 

mid-thickness. For materials thicker 

than 1⁄2-inch, full size Charpy specimens 

must be cut centered at a location as 

near as practicable to a point midway 

between the material’s surface and halfthickness. Except where otherwise 

specified, transversely oriented 

specimens must be used. When 

longitudinal specimens are used, the 

required energy values may not be less 

than 1.5 times the values required for 

transversely oriented specimens. In all 

cases the notch must be cut normal to 

the material’s surface. Test specimens 

must be taken at least one ‘‘t’’ from any 

heat treated edge (where ‘‘t’’ is the 

material’s nominal thickness). 

(b) Drop weight tests. Where required, 

drop weight tests must be conducted for 

no-break performance in accordance 

with ASTM E208 (incorporated by 

reference, see § 54.01–1). For material 

thicknesses between 1⁄2-inch and 5⁄8- 

inch, the ASTM E208 specimen P–3, 

machined to 1⁄2-inch thickness, must be 

used with a stop distance of 0.090-inch. 

In preparing weld specimens for 

dropweight testing, weld reinforcement 

must be ground flush, the hard facing 

bead centered on and transverse to the 

weld, and the notch centered on and 

parallel to the weld axis.

times the maximum allowable working 

pressure stamped on the pressure 

vessel, multiplied by the ratio of the 

stress value ‘‘S’’ at the test temperature

■ 143. Revise § 56.20–9 to read as 

follows: 

§ 56.20–9 Valve construction. 

(a) Each valve must close with a righthand (clockwise) motion of the 

handwheel or operating lever as seen by 

one facing the end of the valve stem. 

Each nonrising-stem valve, leveroperated valve, or other valve where, 

because of design, the position of the 

disc or closure mechanism is not 

obvious must be fitted with an indicator 

to show whether the valve is opened or 

closed. No such indicator is required for 

any valve located in a tank or similar 

inaccessible space when indicators are 

available at accessible sites. The 

operating levers of quarter-turn valves 

must be parallel to the fluid flow when 

open and perpendicular to the fluid 

flow when closed. 

(b) Valves of Class I piping systems 

having diameters exceeding 2 inches 

must have bolted, pressure seal, or 

breech lock bonnets and flanged or 

welding ends. Socket type welding ends 

must meet § 56.30–5(c) and § 56.30– 

10(b)(4). For diameters not exceeding 2 

inches, screwed union bonnet or bolted 

bonnet, or bonnetless valves which 

prevent the stem from screwing out of 

the body may be employed. Outside 

screw and yoke design must be used for 

valves 3 inches and larger for pressures 

above 600 psig. Cast iron valves with 

screwed-in or screwed-over bonnets are 

prohibited. Union bonnet type cast iron 

valves must have the bonnet ring made 

of steel, bronze, or malleable iron. 

(c) Valves must be designed for the 

maximum pressure to which they may 

be subjected, but in no case must the 

design pressure be less than 50 psig. 

The use of wafer type resilient seated 

valves is subject to the requirements of 

§ 56.20–15. 

(d) Disks or disk faces, seats, stems 

and other wearing parts of valves must 

be made of material possessing 

corrosion and heat-resisting qualities 

suitable for the service conditions to 

which they may be subjected. 

(e) Plug cocks must be constructed 

with satisfactory and positive means of 

preventing the plug from becoming 

loosened or removed from the body 

when the plug is operated. 

(f) Cocks must be marked in a straight 

line with the body to indicate whether 

they are open or closed. 

■ 144. Revise § 56.20–15 to read as 

follows: 

§ 56.20–15 Valves employing resilient 

material. 

(a) A valve in which the closure is 

accomplished by resilient nonmetallic 

material instead of a metal to metal seat 

must comply with the design, material, 

construction and testing for valves 

specified in this section. 

(b) Valves employing resilient 

material are divided into three 

categories: Positive shutoff, Category A, 

and Category B, and must be tested and 

used as follows: 

(1) Positive shutoff valves. The closed 

valve must pass less than 10 ml/hr (0.34 

fluid oz/hr) of liquid, or less than 3 l/ 

hr (0.11 cubic ft/hr) of gas per inch 

nominal pipe size through the line at 

full rated pressure after being subjected 

to the fire test requirements of API 607 

(incorporated by reference; see § 56.01– 

2). Packing material must be fire 

resistant. Piping subject to internal head 

pressure from a tank containing oil must 

be fitted with positive shutoff valves 

located at the tank in accordance with 

§ 56.50–60(d). Positive shutoff valves 

may be used in any location in lieu of 

a Category A or Category B valve. 

(2) Category A valves. Category A 

valves may be used in any location 

except where positive shutoff valves are 

required by § 56.50–60(d). To be 

qualified as a Category A valve, the 

valve must meet the fire test and leakage 

requirements of API 607. 

(i) Category A valves are required at 

vital piping system manifolds; 

(ii) Category A valves must be used in 

isolation valves in cross-connects 

between two piping systems, at least 

one of which is a vital system, where 

failure of the valve in a fire would 

prevent the vital system(s) from 

functioning as designed, and 

(iii) Category A valves must be used 

for valves providing closure for any 

opening in the shell of the vessel. 

(3) Category B valves. The closed 

valve will not provide effective closure 

of the line or will permit appreciable 

leakage from the valve after the resilient 

material is damaged or destroyed. 

Category B valves are not required to be

■ 162. Revise § 56.50–1 to read as 

follows: 

§ 56.50–1 General (replaces 122). 

The requirements in this subpart for 

piping systems apply instead of those in 

Section 122 of ASME B31.1 

(incorporated by reference; see § 56.01– 

2). The following installation 

requirements are applicable to all 

systems: 

(a) Where pipes and scuppers are 

carried through watertight or oiltight 

bulkheads, decks or tank tops, or are 

carried through fire control bulkheads 

and decks, the integrity of the structure 

must be maintained. Lead or other heat 

sensitive materials must not be used in 

piping systems in bulkhead or deck 

penetrations where fire would impair 

the integrity of the penetration. (For 

nonmetallic or plastic pipe installations, 

see § 56.60–25(a).) Openings in structure 

through which pipes pass must be 

reinforced where necessary. Metallic 

materials having a melting point of 

1,700 °F or less are considered heat 

sensitive and if used must be suitably 

insulated. 

(b)(1) Pipes piercing the collision 

bulkhead must be fitted with valves 

operable from above the bulkhead deck 

and the valve must be fitted inside the 

forepeak tank adjacent to the collision 

bulkhead. The pipe penetrating the 

collision bulkhead must be welded to 

the bulkhead on both sides. The valve 

body must be of steel or ductile cast 

iron. 

(2) Passenger vessels must not have 

the collision bulkhead pierced below 

the margin line by more than one pipe 

conveying liquids in the forepeak tank. 

(c) Valves and cocks not forming part 

of a piping system are not permitted in 

watertight subdivision bulkheads. 

However, sluice valves or gates in 

oiltight bulkheads of tankships may be 

used if approved by the Marine Safety 

Center. 

(d) Piping must generally not be run 

over switchboards, and must be 

installed as far away from other 

electrical equipment as practicable. 

When such leads are necessary, 

provision must be made to prevent 

leakage from damaging the equipment. 

(e) Stuffing boxes must not be used on 

deep tank bulkheads, double bottoms or 

in any position where they cannot be 

easily examined. This requirement does 

not apply to ore carriers operating on 

the Great Lakes or cargo lines of oil 

tankers. 

(f) Piping systems must be installed so 

that under no condition will the 

operation of safety or relief valves be 

impaired. 

(g)(1) Power actuated valves may be 

used if approved for the system by the 

Marine Safety Center. All power 

actuated valves must have a backup 

manual means of operation. 

(2)(i) Remote valve controls must be 

fitted with nameplates describing the 

applicable system. 

(ii) Remote valve controls must be 

accessible under normal service 

conditions. 

(iii) Remote valve controls, except 

reach rods, must be fitted with 

indicators that show whether the valves 

they control are open or closed. Valve 

position indicating systems must be 

independent of valve control systems. 

(iv) Valve reach rods must be 

adequately protected. 

(v) Solid reach rods must be used in 

tanks containing liquids, except that 

reach rods of constructed of extra-heavy 

pipe may be considered acceptable by 

the OCMI. 

(3) Air-operated remote control valves 

must be provided with self-indicating 

lines at the control boards that indicate 

the desired valve positions, such as 

open or closed. 

(h) Suitable drains must be provided 

at low points of piping systems. 

(i) Valves and cocks must be easily 

accessible. Valves attached to the shell 

of the vessel or to sea chests located 

below deck plating must be operable 

from above the deckplates. 

(j) When welded fabrication is 

employed, a sufficient number of 

detachable joints must be provided to 

facilitate maintenance of machinery. 

(k) Piping systems used where the 

fluid temperature exceeds 150 °F must 

be suitably insulated as necessary to 

preclude injury to personnel. 

(l) Where pipes are run through dry 

cargo spaces they must be protected 

from mechanical injury by a suitable 

enclosure or other means. 

■ 163. Amend § 56.50–10 by revising 

paragraph (b) to read as follows: 

§ 56.50–10 Special gauge requirements. 

* * * * *

(a)(1) The requirements of SOLAS 

Chapter II–1 regulation 35–1 

(incorporated by reference, see § 56.01– 

2) for passenger and cargo ships are 

considered equivalent to this section. 

(2) All vessels except unmanned 

barges must be provided with a 

satisfactory bilge pumping plant capable 

of pumping from and draining any 

watertight compartment except for 

ballast, oil and water tanks. The bilge 

pumping system must be capable of 

operation under all practicable 

conditions after a casualty whether the 

ship is upright or listed. 

(3) Arrangements must be made 

whereby water in the compartments will 

drain to the suction pipes. Where piping 

is led through the forepeak, see § 56.50– 

1(b). 

(4) Where the vessel is to carry 

flammable liquids with a flashpoint 

below 23 °C (74 °F) in enclosed cargo 

spaces, the bilge-pumping system must 

be designed to ensure against 

inadvertent pumping of such liquids 

through machinery spaces. 

(5) For vessels constructed on or after 

June 9, 1995, and on an international 

voyage, arrangements must meet the 

requirements of SOLAS Chapter II–1 

regulation 35–1 to drain the enclosed 

cargo spaces on either the bulkhead 

deck of a passenger vessel or the 

freeboard deck of a cargo vessel. 

(b) Passenger vessels must have 

provision made to prevent the 

compartment served by any bilge 

suction piping from being flooded in the 

event the pipe is severed or otherwise 

damaged by collision or grounding in 

any other compartment. Where the 

piping is located within one-fifth of the 

beam of the side of the vessel or is in 

a duct keel, a nonreturn valve must be 

fitted to the end of the pipe in the 

compartment which it serves. 

(c)(1) Each bilge suction must lead 

from a manifold unless otherwise 

approved by the Marine Safety Center.

As far as practicable, each manifold 

must be in, or capable of remote 

operation from, the same space as the 

bilge pump. In either case, the manifold 

must be capable of being locally 

controlled from the floorplates. As far as 

practicable, each overboard-discharge 

valve for a bilge system must comply 

with the requirements governing 

location and accessibility for suction 

manifolds. Except as otherwise

Lakes routes, the main circulating pump 

is to be fitted with a direct bilge suction 

for the machinery space. The diameter 

of such suctions must not be less than 

two-thirds the diameter of the main sea 

injection. Other independent power 

pumps in the machinery space may be 

approved by the Commandant if the 

main circulating pump is not suitable. 

(2) On passenger vessels propelled by 

internal combustion engines and 

operating on an international voyage or 

on ocean, coastwise, or Great Lakes 

routes, the largest available pump in the 

engine room is to be fitted with the 

direct bilge suction in the machinery 

space. The area of the suction pipe is to 

be equal to the full suction inlet of the 

pump. 

* * * * * 

(g) Each individual bilge suction must 

be fitted with a suitable strainer having 

an open area of not less than three times 

that of the suction pipe. In addition a 

mud box or basket strainer must be 

fitted in an accessible position between 

the bilge suction manifold and the 

pump.

The bilge suctions must be blanked-off 

when oil or ballast is carried. 

(k) Where bilge and ballast piping is 

led through tanks, except ballast piping 

in ballast tanks, means must be 

provided to minimize the risk of 

flooding of other spaces due to pipe 

failure. In this regard, such piping may 

be in a watertight pipe tunnel, or the 

piping may be of Schedule 80 pipe wall 

thickness, fitted with expansion bends, 

with all joints welded. Alternative 

designs may be approved by the Marine 

Safety Center. Where a pipe tunnel is 

installed, the watertight integrity of the 

bulkheads must be maintained. No 

valve or fitting may be located within 

the tunnel if the pipe tunnel is not of 

sufficient size to afford access.

■ i. In paragraph (g), remove the word 

‘‘shall’’ wherever it appears and add, in 

its place, the word ‘‘must’’; and 

■ j. Revise paragraphs (h) and (i). 

The revisions read as follows: 

§ 56.50–95 Overboard discharges and 

shell connections. 

(a)(1) All inlets and discharges led 

through the vessel’s side must be fitted 

with efficient and accessible means, 

located as close to the hull penetrations 

as is practicable. 

* * * * * 

(b) * * * 

(2) Discharges led through the shell 

originating either from spaces below the 

freeboard deck or from within enclosed 

superstructures and equivalent 

deckhouses on the freeboard deck as 

defined in § 42.13–15(i) of subchapter E 

(Load Lines) of this chapter, must be 

fitted with efficient and accessible 

means for preventing water from 

passing inboard. Normally each separate 

discharge must have one automatic 

nonreturn valve with a positive means 

of closing it from a position above the 

freeboard deck. Where, however, the 

vertical upward distance from the 

summer load line to the inboard end of 

the discharge pipe through which 

flooding can take place exceeds 0.01L, 

the discharge may have two automatic 

nonreturn valves without positive 

means of closing, provided that the 

inboard valve is always accessible for 

examination under service conditions. 

Where that vertical distance exceeds 

0.02L a single automatic nonreturn 

valve without positive means of closing 

is acceptable. In an installation where 

the two automatic nonreturn valves are 

used, the inboard valve must be above 

the tropical load line. The means for 

operating the positive action valve must 

be readily accessible and provided with 

an indicator showing whether the valve 

is open or closed. A notice must be 

posted at the operating station to the 

effect that the valve must not be closed 

except as required in an emergency. 

* * * * * 

(d)(1) Sea inlets and discharges, such 

as used in closed systems required for 

the operation of main and auxiliary 

machinery, as in pump connections or 

scoop injection heat exchanger 

connections, need not meet the 

requirements of paragraphs (b)(1) and 

(2) of this section but instead must be 

fitted with a shutoff valve located as 

near the shell plating as practicable, and 

may be locally controlled if the valve is 

located in a manned machinery space. 

These controls must be readily 

accessible above the floor plates. 

Manned machinery spaces include the 

main machinery space and are either 

attended by the crew or are automated 

in accordance with part 62 of this 

subchapter to be comparable to an 

attended space. 

* * * * * 

(e) * * * 

(2) Seachests and other hull fittings 

must be as short as possible and located 

so as to minimize the possibility of 

being blocked or obstructed. 

* * * * * 

(f) Valves required by this section and 

piping system components outboard of 

such required valves must be of a steel, 

bronze, or ductile cast iron specification 

listed in table 1 to § 56.60–1. Lead or 

other heat sensitive materials having a 

melting point of 1,700 °F. or less must 

not be used in such service where the 

deterioration of the piping system in the 

event of fire would give rise to danger 

of flooding. Brittle materials such as cast 

iron must not be used in such service. 

Where nonmetallic materials are used in 

a piping system, and shell closures are 

required by this section, a positive 

closure metallic valve is required (see 

also § 56.60–25). 

* * * * * 

(h) Where deck drains, soil lines, and 

sanitary drains discharge through the 

shell in way of cargo tanks on tank 

vessels, the valves required by this 

section must be located outside the 

cargo tanks. These valves must meet the 

material requirements of paragraph (f) of 

this section. The piping led through 

such tanks must be fitted with 

expansion bends where required, and 

must be of steel pipe having a wall 

thickness of not less than Schedule 60, 

except that the use of suitable corrosionresistant material of lesser thickness 

will be given special consideration by 

the Commandant. All pipe joints within 

the tanks must be welded. Soil lines and 

sanitary drains which pass through 

cargo tanks must be provided with 

nonreturn valves with positive means of 

closing or other suitable means for 

preventing the entrance of gases into 

living quarters. 

(i) Sea valves must not be held open 

or closed with locks.

The revisions read as follows: 

§ 56.50–105 Low-temperature piping. 

(a) Class I–L. Piping systems 

designated to operate at temperatures 

below 0 °F. and pressures above 150 

psig must be of Class I–L. Exceptions to 

this rule may be found in the individual 

requirements for specific commodities 

in subchapters D, I, and O of this 

chapter. The following requirements for 

Class I–L piping systems must be 

satisfied: 

(1) Materials. All materials used in 

low temperature piping systems must be 

selected from among those 

specifications listed in table 2 to 

§ 56.50–105 and must satisfy all of the 

requirements of the specifications, 

except that: 

(i) The minimum service temperature 

as defined in § 54.25–10(a)(2) of this 

subchapter must not be colder than that 

shown in table 2 to § 56.50–105; and 

(ii) The material must be tested for 

low temperature toughness per ASTM 

E23 (incorporated by reference, see 

§ 56.01–2), Figure 4. The toughness 

testing requirements of subpart 54.05 of 

this subchapter must be satisfied for 

each particular product form. Charpy Vnotch tests must be conducted at 

temperatures not warmer than 10 °F. 

below the minimum service temperature 

of the design, except that for service 

temperatures of ¥320 °F. and below, the 

impact test may be conducted at the 

service temperature. The minimum 

average energy must not be less than 

that shown in table 2 to § 56.50–105. In 

the case of steels conforming to the 

specifications of table § 54.25–20(a) of 

this subchapter the minimum lateral 

expansion must not be less than that 

required in § 54.25–20 of this 

subchapter. The minimum energy 

permitted for a single specimen and the 

minimum subsize energies must be 

those obtained by multiplying the 

average energy shown in table 2 to 

§ 56.50–105 by the applicable fraction 

shown in table 1 to § 56.50–105(a)(1)(ii).

may be specially approved by the 

Marine Safety Center. Similarly, 

aluminum alloys and other materials 

not covered in table 2 to § 56.50–105 

may be specifically approved by the 

Marine Safety Center. 

* * * * * 

(b) Class II–L. Piping systems 

designed to operate at temperatures 

below 0 °F. and pressures not higher 

than 150 psig must be of Class II–L. 

Exceptions to this rule may be found in 

the individual requirements for specific 

commodities in subchapter D (Tank 

Vessels) and subchapter I (Cargo and 

Miscellaneous Vessels), both of this 

chapter. The following requirements for 

Class II–L piping systems must be 

satisfied:

§ 56.50–110 [Amended] 

■ 186. In § 56.50–110(b), remove the 

words ‘‘which is’’. 

■ 187. Revise § 56.60–1 to read as 

follows: 

§ 56.60–1 Acceptable materials and 

specifications (replaces 123 and Table 126.1 

in ASME B31.1). 

(a)(1) The material requirements in 

this subpart must be followed in lieu of 

those in 123 in ASME B31.1 

(incorporated by reference; see § 56.01– 

2). 

(2) Materials used in piping systems 

must be selected from the specifications 

that appear in table 1 to § 56.60–1 of this 

section or table § 56.60–2, ASTM F1155 

(incorporated by reference; see § 56.01– 

2), or they may be selected from the 

material specifications of Sections I or 

VIII of the ASME BPVC (both 

incorporated by reference; see § 56.01– 

2) if not prohibited by a regulation of 

this subchapter. Table 1 to § 56.60–1(a) 

contains only pipe, tubing, and fitting 

specifications. Determination of 

acceptability of plate, forgings, bolting, 

nuts, and castings may be made by 

reference to the ASME BPVC as 

previously described. Additionally, 

accepted materials for use as piping 

system components appear in table 

§ 56.60–2. Materials conforming to 

specifications not described in this 

subparagraph must receive the specific 

approval of the Marine Safety Center. 

Materials listed in Table 126.1 of ASME 

B31.1 are not accepted unless 

specifically permitted by this paragraph. 

(b) Components made in accordance 

with the commercial standards listed in 

Table 56.60–1(b) of this section and 

made of materials complying with 

paragraph (a) this section may be used 

in piping systems within the limitations 

of the standards and within any further 

limitations specified in this subchapter. 

Note 1 to § 56.60–1: Table 1 to 

§ 56.60–1 replaces Table 126.1 in ASME 

B31.1 and sets forth specifications of 

pipes, tubing, and fittings intended for 

use in piping-systems. The first column 

lists acceptable standards from ASTM 

(all incorporated by reference; see 

§ 56.01–2); the second lists those from 

ASME (all incorporated by reference; 

see § 56.01–2). The Coast Guard will 

consider use of alternative pipes, tubing, 

and fittings when it receives 

certification of their mechanical 

properties. Without this certification it 

will restrict use of such alternatives to 

piping-systems inside heat exchangers 

that ensure containment of the material 

inside pressure shells.

welded butt joints or equivalent single 

welded butt joints for pipe diameters 

exceeding three-fourth inch nominal 

pipe size. The use of a single welded 

butt joint employing a backing ring 

(note restrictions in paragraph (b)(3)(iv) 

of this section) on the inside of the pipe 

is an acceptable equivalent for Class I 

and Class II–L applications, but not 

permitted for Class I–L applications. 

Single welded butt joints employing 

either an inert gas for first pass backup 

or a consumable insert ring may be 

considered the equivalent of a double 

welded butt joint for all classes of 

piping and is preferable for Class I–L 

and II–L systems where double butt 

welds cannot be used. A first pass inert 

gas backup is intended to mean that the 

inside of the pipe is purged with inert 

gas and that the root is welded with the 

inert gas metal arc (mig) or inert gas 

tungsten arc (tig) processes. For single 

welded joints, where possible, the 

inside of the joint must be examined 

visually to assure full penetration. 

Radiographic examination of at least 20 

percent of single welded joints to check 

for penetration is required for all Class 

I and Class I–L systems regardless of 

size following the requirements of 

§ 56.95–10. Ultrasonic testing may be 

utilized in lieu of radiographic 

examination if the procedures are 

approved.

finished weld must be made by a 

qualified welder. Tack welds which 

have cracked must be removed.

inspector. 

§ 56.95–5 [Amended] 

■ 215. In § 56.95–5, remove the word 

‘‘shall’’ wherever it appears and add, in 

its place, the word ‘‘must’’. 

■ 216. Revise § 56.95–10 to read as 

follows: 

§ 56.95–10 Type and extent of examination 

required. 

(a) General. The types and extent of 

nondestructive examinations required 

for piping must be in accordance with 

this section and Table 136.4 of ASME 

B31.1 (incorporated by reference; see 

§ 56.01–2). In addition, a visual 

examination must be made. 

(1) 100 percent radiography is 

required for all Class I, I–L, and II–L 

piping with wall thickness equal to or 

greater than 10 mm (.393 in.). 

Note 1 to paragraph (a)(1): 

Throughout this this section, where for 

some reason, such as joint 

configuration, radiography is not 

applicable, another approved 

examination may be utilized. 

(2) Nondestructive examination is 

required for all Class II piping equal to 

or greater than 18 inches nominal 

diameter regardless of wall thickness. 

Any test method acceptable to the 

Officer in Charge, Marine Inspection 

may be used. 

(3) Nondestructive examinations of 

other piping systems are required only 

when deemed necessary by the Officer 

in Charge, Marine Inspection (OCMI). 

(b) Visual examination. Visual 

examination consists of observation by 

the marine inspector either before, 

during, or after manufacture, 

fabrication, assembly or test. All welds, 

pipe and piping components must 

comply with the limitations on 

imperfections specified in the product 

specification or with the limitations on 

imperfections specified in § 56.70– 

15(b)(7) and (8), and (c), as applicable. 

(c) Nondestructive types of 

examinations—(1) 100 Percent 

radiography. Where 100 percent 

radiography is required, each weld in 

the piping must be completely 

radiographed. If a butt weld is examined 

by radiography, for either random or 

100 percent radiography, the method 

used must be as follows: 

(i) X-ray or gamma ray method of 

radiography may be used. The selection 

of the method must be dependent upon 

its adaptability to the work being 

radiographed. The procedure to be 

followed must be as indicated in PW– 

51 of Section I of the ASME BPVC 

(incorporated by reference; see § 56.01– 

2). 

(ii) If a piping component or a weld 

other than a butt weld is radiographed, 

the method used must be in accordance 

with UW–51 of Section VIII of the 

ASME BPVC (incorporated by reference; 

see § 56.01–2). 

(2) Random radiography. Where 

random radiography is required, one or 

more welds may be completely or 

partially radiographed. Random 

radiography is desirable in field 

welding, where conditions such as 

position, temperatures, and cleanliness 

are not as controlled as in shop welding. 

It may be employed whenever an Officer 

in Charge, Marine Inspection questions 

a pipe weld not otherwise required to be 

tested. The standards of acceptance are 

the same as for 100 percent radiography. 

(3) Ultrasonic. Where 100 percent 

ultrasonic testing is specified, the entire 

surface of the weld being inspected 

must be covered using careful methods 

to be sure that a true representation of 

the actual conditions is obtained. The 

procedures to be used must be 

submitted to the Commandant for 

approval. 

(4) Liquid penetrant. Where liquid 

penetrant examination is required, the 

entire surface of the weld being 

examined must be covered. The 

examination must be performed in 

accordance with appendix VIII to 

Section VIII of the ASME BPVC. The 

following standards of acceptance must 

be met: 

(i) All linear discontinuities and 

aligned penetrant indications revealed 

by the test must be removed. Aligned 


jspears on DSK121TN23PROD with PROPOSALS2
Federal Register / Vol. 86, No. 199 / Tuesday, October 19, 2021 / Proposed Rules 57969 

penetrant indications are those in which 

the average of the center-to-center 

distances between any one indication 

and the two adjacent indications in any 

straight line is less than three-sixteenths 

inch. All other discontinuities revealed 

on the surface need not be removed 

unless the discontinuities are also 

revealed by radiography, in which case 

the pertinent radiographic specification 

applies. 

(ii) [Reserved] 

(5) Magnetic particle. Where magnetic 

particle testing is required, the entire 

surface of the weld being examined 

must be covered. The testing must be 

performed in accordance with 

Appendix VI to Section VIII of the 

ASME BPVC. The following standards 

of acceptance are required for welds. All 

linear discontinuities and aligned 

indications revealed by the test must be 

removed. Aligned indications are those 

in which the average of the center-tocenter distances between any one 

indication and the two adjacent 

indications in any straight line is less 

than three-sixteenths inch. All other 

revealed discontinuities need not be 

removed unless the discontinuities are 

also revealed by radiography, in which 

case the requirements of paragraph 

(c)(1) of this section must be met. 

■ 217. Amend § 56.97–1 as follows: 

■ a. In paragraph (a), remove the text 

‘‘46 CFR’’ and add, in its place, the 

symbol ‘‘§ ’’; 

■ b. Revise the introductory text of 

paragraph (b); 

■ c. Redesignate footnote 1 to paragraph 

(b)(2)(i) as Note 1 to paragraph (b)(2)(i); 

■ d. Revise paragraph (b)(2)(ii); 

■ e. Designate the Note as Note 1 to 

paragraph (b)(3); and 

■ f. Remove paragraph (b)(4). 

The revisions read as follows: 

§ 56.97–1 General (replaces 137). 

* * * * * 

(b) Leak tightness. It is mandatory that 

the piping constructed demonstrates 

leak tightness. Except where otherwise 

permitted, this requirement must be met 

by a hydrostatic leak test prior to initial 

operations. Where a hydrostatic test is 

not practicable, a pneumatic test 

(§ 56.97–35) or initial service leak test 

(§ 56.97–38) may be substituted if 

approved by the Commandant. 

* * * * * 

(2) * * * 

(ii) Piping systems are to be used in 

services where traces of water cannot be 

tolerated and, whenever possible, the 

piping subassemblies or system have 

been previously hydrostatically tested to 

the pressure required in § 56.97–30(e).

* * * * * 

(h) All cracks permitted to be repaired 

under this subpart must be excavated to 

sound metal by grinding, flame or arc 

gouging or chipping out the defective 

metal to form a clean welding groove. 

Either a V groove or U groove wherein 

complete penetration of the weld metal 

is secured may be used. After 

excavation is completed and prior to 

welding, the excavated area must be 

examined by magnetic particle, dye 

penetrant, or other acceptable test 

method. When the reverse side of the 

weld is accessible the root of the weld 

must be chipped or ground out to insure 

a clean surface of the originally 

deposited metal and the resultant 

groove welded to obtain a sound weld 

having complete penetration. When the 

weld cannot be back chipped because 

the reverse side is inaccessible, a 

backing strip or other approved means 

of assuring full penetration must be 

employed. 

(i) During welding of cracks a preheat 

must be maintained by controlled 

temperatures. The degree of preheat 

must be determined by the rules listed 

in accordance with the materials Pnumber groupings of PW–38, Section I 

of the ASME BPVC, appendix R, Section 

VIII of the ASME BPVC, and Appendix 

D, Section IX of the ASME BPVC (all 

incorporated by reference; see § 59.01–

reinforced area must be renewed, but 

where the staybolts are fitted with nuts, 

the nuts may be removed and after 

reinforcing has been applied, collars 

may be welded around the staybolts in 

lieu of the nuts. Such reinforced areas 

must not exceed 400 square inches nor 

more than 30 inches in one direction. 

Two such areas in any one plate may be 

reinforced: Provided, that the distance 

between the reinforced surfaces is not 

less than 30 inches.

replacing it with a new plate, the edges 

of the new plate to be welded in 

position. In such cases, new staybolts 

must be fitted, and where welding is 

performed through a line of staybolts, 

welded collars must be used to attach 

the staybolts. 

(f) Eroded seams of welded pressure 

vessels may be repaired by rewelding 

the wasted portion. The wasted section 

of the seam must be excavated 

sufficiently by grinding, flame or arc 

gouging or chipping to ensure proper 

weld penetration. Rewelded seams must

§ 61.05–1 [Amended] 

■ 315. In § 61.05–1, remove the text 

‘‘part 52’’ and add, in its place, the text 

‘‘part 52 of this subchapter.’’ 

■ 316. Amend § 61.05–5 as follows: 

■ a. Revise paragraph (a); and 

■ b. In paragraph (b), remove the word 

‘‘shall’’ wherever it appears and add, in 

its place, the word ‘‘must’’. 

The revision reads as follows: 

§ 61.05–5 Preparation of boilers for 

inspection and test. 

(a) For internal inspection, manhole 

and handhold plates, and washout plugs 

must be removed as required by the 

marine inspector and the furnace and 

combustion chambers must be 

thoroughly cooled and cleaned. 

* * * * * 

■ 317. Amend § 61.05–10 as follows: 

■ a. Revise paragraph (a); 

■ b. In paragraphs (b), (c), (d), and (e), 

remove the word ‘‘shall’’ wherever it 

appears and add, in its place, the word 

‘‘must’’; 

■ c. Revise paragraphs (f) and (g); and 

■ d. Redesignate table 61.05–10 as table 

§ 61.05–10. 

The revisions read as follows: 

§ 61.05–10 Boilers in service. 

(a) Each boiler, including superheater, 

reheater, economizer, auxiliary boiler, 

low-pressure heating boiler, and unfired 

steam boiler, must be available for 

examination by the marine inspector at 

intervals specified by table § 61.05–10, 

and more often if necessary, to 

determine that the complete unit is in 

a safe and satisfactory condition. 

* * * * * 

(f) The marine inspector may require 

any boiler to be drilled or gaged to 

determine actual thickness any time its 

safety is in doubt. At the first inspection 

for certification after a firetube or flue 

boiler has been installed for 10 years, it 

must be gaged to determine the extent 

of deterioration. Thickness will be 

measured at or near the waterline, at the 

bottom and at such other places deemed 

necessary by the marine inspector. 

Examination may be by drilling or a 

nondestructive means acceptable to the 

marine inspector. Prior to the use of a 

nondestructive method of examination, 

the user must demonstrate to the marine 

inspector that results having an 

accuracy within plus or minus 5 percent 

are consistently obtainable. 

(g) If the thickness is found to be less 

than the original thickness upon which 

the maximum allowable working 

pressure (MAWP) was based, the 

MAWP must be recalculated. The 

thickness of the thinnest measured 

portion must be used in this calculation. 

Either the design formulas given in this 

subchapter or the ones in effect when 

the boiler was contracted for or built 

may normally be used in this 

recalculation. In no case will an 

increase in the pressure allowed be 

made. 

* * * * * 

§ 61.05–15 [Amended] 

■ 318. Amend § 61.05–15 as follows: 

■ a. Remove the word ‘‘shall’’ wherever 

it appears and add, in its place, the 

word ‘‘must’’; and 

■ b. Remove the text ‘‘Table 61.05–10’’ 

wherever it appears and add, in its 

place, the text ‘‘table § 61.05–10’’. 

§ 61.05–20 [Amended] 

■ 319. In § 61.05–20, remove the word 

‘‘shall’’ and add, in its place, the word 

‘‘must’’. 

■ 320. Amend § 61.10–5 as follows: 

■ a. Revise paragraph (g); and 

■ b. In paragraph (h)(3), remove the text 

‘‘(Mobile Offshore Drilling Units),’’ and 

add, in its place, the text ‘‘(Mobile 

Offshore Drilling Units), all of this 

chapter,’’. 

The revision reads as follows: 

§ 61.10–5 Pressure vessels in service. 

* * * * * 

(g) Bulk storage tanks. (1) Each bulk 

storage tank containing refrigerated 

liquefied CO2 for use aboard a vessel as 

a fire-extinguishing agent must be 

subjected to a hydrostatic test of 1.5 

times the maximum allowable working 

pressure in the 10th year of the 

installation and at 10-year intervals 

thereafter. After the test, the tank should 

be drained and an internal examination 

made. Parts of the jacket and lagging 

designated by the marine inspector must 

be removed at the time of the test so the 

marine inspector may determine the 

condition of the tank. 

(2) In lieu of the requirements 

contained in paragraph (g)(1) of this 

section, in the 10th year of installation 

and at 10-year intervals thereafter, each 

bulk storage tank containing refrigerated 

liquefied CO2 for use aboard a vessel as 

a fire-extinguishing agent which 

contains a manhole or means to enter, 

may undergo an internal examination by 

a marine inspector. Bulk storage tanks 

which have been satisfactorily 

examined internally by a marine 

inspector and in which no defects have 

been found which impair the safety of 

the pressure vessel will not require a 

hydrostatic test. When a defect is found 

during the internal examination that, in 

the judgment of the marine inspector, 

may affect the safety of the pressure 

vessel, the pressure vessel must be 

hydrostatically tested at a pressure of 

1.5 times the maximum allowable 

working pressure, unless alternative 

means, acceptable to the Officer In 

Charge, Marine Inspection, are used to 

ensure the safe operation of the pressure 

vessel.
